Installing on Windows

If you change the install path, make sure it contains only Latin characters.
Launch ZEUS and register — the license is tied to your account.

What to do after installation — first launch →

Windows may show a SmartScreen warning — click More info → Run anyway. This is normal for apps without an expensive publisher certificate.

Updates install automatically when you launch the program.

Installing on macOS

Download ZeusInstaller-2.15.dmg.
Open the .dmg and drag Zeus.app to the Applications folder.
On first launch, go to System Settings → Privacy & Security and allow ZEUS to run.

If it still won't open — Terminal method:

Applications → Utilities → Terminal, run each command in order:

sudo spctl --master-disable
sudo xattr -rd com.apple.quarantine /Applications/Zeus.app
sudo chmod -R 755 /Applications/Zeus.app

Press Return after each command. When typing your password, no characters will appear — that's normal.
